💥 Your Impact
Your role will play a major role in our success because…
You'll be the builder who crafts the reliable, scalable systems that power Coverflex's compensation platform, enabling thousands of companies to transform how they reward and support their people. Every API you design, every database optimization you implement, and every architectural decision you make will directly impact the financial wellbeing of hundreds of thousands of employees who depend on Coverflex for their benefits, insurance, and flexible compensation.
You'll be embedded within a focused product team, working on a specific vertical with clear purpose and ownership. As a product engineer, you won't just write code - you'll shape what gets built. You'll collaborate closely with product managers and designers from discovery through delivery, bringing technical perspective to product decisions, identifying opportunities, and ensuring we're solving the right problems in the right way. You'll own meaningful problems end-to-end and ship features that make complex compensation simple, compliant, and delightful.

You’ll know you’re successful when, after 90 days, you’ve…

• Shipped meaningful features that directly impact your team's key metrics - whether that's processing more transactions, reducing operational friction, or enabling new product capabilities

• Built reliable, scalable infrastructure that handles production load with confidence, proper monitoring, and graceful degradation

• Improved system quality and performance through thoughtful optimisations, reduced latency, better error handling, or enhanced data consistency

• Established solid foundations by implementing proper testing coverage, observability, documentation, and patterns that set your team up for sustained velocity

• Demonstrated technical ownership by leading features end-to-end with minimal oversight, making sound architectural decisions, and owning outcomes - not just outputs

• Elevated the team through constructive code reviews, knowledge sharing, pairing with teammates, and contributing to engineering standards and best practices

• Collaborated effectively with product by bringing technical perspective to discovery, identifying opportunities, challenging assumptions, and ensuring we build the right thing the right way

How we’ll measure success:
Success means shipping features that move the needle on your team's objectives week over week. You'll see measurable impact through the metrics that matter for your vertical - whether that's transaction success rates, processing time, user adoption, or operational efficiency.
Your systems will be reliable: stable deployments, comprehensive monitoring with actionable alerts, well-documented runbooks, and architecture that scales with demand.
Your team will move faster because of the foundations you build - reusable patterns, clear abstractions, and technical decisions that compound over time.
Product won't need to chase you for status updates because you're proactively communicating progress, blockers, and trade-offs.
You'll know you've succeeded when your features are live and impacting users, your code is maintainable and well-tested, and your team is stronger because of your contributions.
⚡ Reality Check - What Makes This Role Hard
Let's be real - here's what makes this role challenging:
Business and product move fast. You'll need to ship features quickly while maintaining system stability and reliability. Product cycles are tight, but every feature you build must be properly tested, monitored, and resilient from day one. You're handling people's money and benefits, which requires extra care and caution in everything you ship.
You're navigating lots of moving parts. Compensation isn't simple - it touches payments, benefits, insurance, compliance, and integrations with external providers. Your changes might affect multiple systems, and you'll need to coordinate across product teams, operations, data, and infrastructure without clear-cut boundaries. Understanding the broader context and anticipating downstream impacts is critical.
Every country adds complexity. We operate in Portugal, Italy, and Spain, and each market has different regulations, tax rules, benefit types, and compliance requirements. What works in one country may not work exactly the same way in another. You'll need to build systems that are flexible enough to handle these nuances without becoming unmaintainable or slowing down your ability to ship.
